CHARLES G. MAHANA, EARL ID. GLIDDEN, AND MILTON P. LAURENT, OF THREE RIVERS, MICHIGAN, ASSIGNOBS TO FAIRBANKS MORSE tic COMPANY, OF CHI- GAGO, ILLINOIS, A CORPORATION.

RAILWAY MOTOR-CAR.

Application filed April 26, 1920.

To all whom it may concern Be it known that we, CHARLES G. MAHANA, EARL D. GLIDDEN, and MILTON P. LAURENT, citizens of the United States, residing at Three Rivers, county of St. Joseph, State of Michigan, have invented certain new and use ful Improvements in Railway lVlotor-Cars, of which the following is a specification.

This invention relates to improvements in railway motor cars.

The main object of this invention is to provide an improved railway motor car which is light in weight so as to permit its being handled by one man in placing on or removing from the track and at the same time is not likely to leave the track when in use.

A further object is to provide an improved railway motor car having these advantages which is quite simple and economical in structure and very durable in use.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

We accomplish the objects of our invcntion by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a plan view of a railway motor car embodying the features of our invention, certain parts being shown conventionally for convenience in illustration.

Fig. IT is a rear elevation.

'Fig. III is a detail View partially in transverse section on a broken line correspond ing to line 3-3 of Fig. V, showing details of the engine mounting.

Fig. IV is a detail section on a line corresponding to line 4-4: of Fig. IT showing de tails of one ofthe axle supporting bearings.

Fig. V is an inverted view of the engine supporting saddle.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, we provide a frame comprising a front sill or cross mem- Specification of Letters Patent.

ber 1, and rear sill or cross member 2. These are connected at one side by the longitudinal side member 3 and at the other side by a pair of longitudinal sills l. The longitudinal sills 4 are extended beyond the cross members to provide handles 5. The connections for these cross members and longitudinal members are indicated conventionally.

We preferably provide a diagonally disposed brace 6 secured at its front end to the front cross member at 7 adjacent to the in ner of the pair of longitudinal sills l. The rear end of this brace is secured to the rear cross member at. 8 adjacent the rear end of the side member.

A narrow deck 9 is secured to the cross members and constitutes a frame member, the tool box 10 being provided on this deck and also a box 11 to receive tools or the like.

The seat, in the structure illustrated, consists of uprights 12 mounted on the longitudinal sills 4 and having a flat top 13 provided with end rails 14. /Vith the parts thus arranged we secure a light and very rigid frame.

The spindles 15 for the front wheels 16 are mounted on the ends of the front cross member 1.

The axle 17, for the rear wheels 18, is a live axle and is supported at its ends in bearings 19 on the hangers 20.

It will be noted that the seat is well to one side, but being between the wheels the weight does not tend to overbalance the car as is the case where the seat is directly over the two wheels on one side of the car as is the case in nearly all motor cars of this general type.

The engines 21 are shown mainly conventionally, and are provided with crank cases 22 having opposed inwardly projecting bearings 23 for the crank shaft 24 which, in the structure illustrated, is common to-both engines. The engines are mounted on the saddle 25secured on the under sides of the longitudinal sills 4:, the saddle extending from sill to sill and constituting means for sup porting the engines in a fixed or positive relation to each other.

The crank shaft 24 is provided with a gear 26 which meshes with the gear 27 on the axle 17. To prevent the springing of the axle and to hold the gears in proper meshing relation we provide a bearing 28 secured to the rear end of the crank casing vide a railway motor car which may be run at highspeeds without danger otleavmg thetrack an'dat the sametime one which is light in weight and may 'be e'asily managed to place upon or remove from the track by a single operator.
